Just went to walmart and was looking at lawn seed and found some pennington brand seed that they are now coating there lawn seed with mycorrhiza.I have also found that more specalized mixes are coming out with this mycorriza in it.It just shows you the interest of this product is expanding very quickly and I think you will keep seeing more and more products that have this. Ihave have used it on my last three grows and have found it makes alot of diference in the size and quality of your plants.I therefore highly recommend that growers give it a try and i'm sure you will be pleased with the results.:key:
